About cocosharon

Small studio.
Well-crafted products.

cocosharon is an independent web & app studio in South Korea. We make small tools — one clear job each, a calm interface, and real respect for the person using it. invitoo, Haulo and Practice TOPIK are all out, and there will be more. A few principles hold across all of them:

Design-led

Clean, focused interfaces that stay out of your way. Every screen earns its place.

Privacy-minded

We collect only what a product needs to work. In Haulo, guest mode keeps your data on your device.

Independent

A small team that answers to the people using our apps, not investors.

FAQ

Questions, answered.

What is invitoo?

invitoo makes digital invitations for weddings, quinceañeras, birthdays and other celebrations across Latin America. You build one in minutes and share a single link on WhatsApp — guests confirm from that link, and the photos they take gather in a shared album. It’s live at invitoo.app.

What languages is invitoo in?

Spanish, English and Portuguese. invitoo is built for Latin America.

Do my guests need to install anything?

No. You share one link and it opens in the browser — there is nothing for your guests to download or sign up for.

Is Haulo out?

Yes — Haulo is out on the App Store and Google Play.

Is Haulo free?

Yes. The core app is free, supported by ads. An optional Pro subscription unlocks extra features, billed through your App Store or Google Play account and cancellable anytime in your store settings.

Do I need an account to use Haulo?

No. You can use Haulo as a guest, and everything stays on your device. Sign in with Google, Apple, Facebook, or Kakao only if you want your data synced across devices.

What happens to the photos Haulo scans?

AI Scan photos are processed just long enough to read item names and prices into your list — they’re handled transiently and never used to identify you. Details are in Haulo’s Privacy Policy.

What is Practice TOPIK?

Practice TOPIK helps people preparing for the TOPIK, the Test of Proficiency in Korean, keep track of exam dates and registration windows, find test centers, and practice by level — in Spanish, English, Portuguese and Hindi. Dates, test centers and the level calculator are free; the full practice library is part of an optional paid plan. It’s live at practicetopik.com. It’s an independent service, not affiliated with NIIED or topik.go.kr, so always confirm a date on the official site before you register.
